From spaceflightnow.com:

The 197-foot-tall (60-meter) rocket, propelled by an RD-180 main engine and five solid rocket boosters, is set for liftoff during a two-hour launch window Wednesday that opens at 12:15 a.m. EDT (0415 GMT).

The AEHF 4 mission will be the 79th flight of an Atlas 5 rocket, and the fifth Atlas 5 launch of 2018.

Built by Lockheed Martin, the AEHF 4 satellite joins three previous satellites in the AEHF constellation launched by Atlas 5 rockets in 2010, 2012 and 2013. With four AEHF satellites in orbit, the Air Force’s new generation of secure, nuclear-hardened voice, video and data relay spacecraft will provide global coverage.
